Ryan and Rael had some money at first. Ryan received 2 times as much money as Rael every day. At the end of 4 days, both of them had the same amount of money. If Rael had $1280 at first and Ryan had $1680 at the end of those 4 days, what is the ratio of Ryan's money to the total amount of money at first?

$1680 |
$1680 |
Amount that Rael received every day
= 1680 - 1280
= $400
1 u = 400
Amount that Ryan received every day
= 2 u
= 2 x 400
= $800
Amount that Ryan had at first
= 1680 - 800
= $880
Total amount that Ryan and Rael had at first
= 1280 + 880
= $2160
Ryan's amount : Total amount
880 : 2160
11 : 27
Answer(s): 11 : 27
